test_gsm0808_enc_dec_speech_codec_with_cfg: initialize properly
The uninitialized members of enc_sc sporadically hit address sanitizer failure
during gsm0808_test, like:
../../../../src/libosmocore/src/gsm/gsm0808_utils.c:187:8: runtime error: load of value 13, which is not a valid value for type '_Bool'
../../../../src/libosmocore/src/gsm/gsm0808_utils.c:191:8: runtime error: load of value 119, which is not a valid value for type '_Bool'
How the test survived so long is a mystery to me; as soon as some uninitialized
members would by coincidence not be zero, the test should always have failed at
OSMO_ASSERT(memcmp(&enc_sc, &dec_sc, sizeof(enc_sc)) == 0).
